Does self restraint, tolerance, patience,composure and silence convey the message across, without reaction or communication on your part ?

Imagine someone speaks angrily with you,

He/She uses profane language to address you,

He/She disrespects you or uses the most disrespectful language..

He/She tries to insult you around everybody...

Still...

You don't react or display any response,

You don't answer his questions by turning your face away...

You remain calm, relaxed, silent with your body standing still and fearless, as if it doesn't make any difference to what he has to say, ask or speak..

What do you think would happen to that person ?

Would his moral judgement and his impression of you really change ?
